Description

SCOPE OF THE INVENTION The present invention relates to a portable electronic device designed as a universal remote control controller for controlling multiple electronic devices. In particular, it discloses an IoT-enabled smart ring that can control various devices by means of gesture recognition, integration of voice commands, secure signal mapping, and adaptive multi-sensor technology. The system is designed to provide a compact, lightweight and intuitive control interface that replaces conventional remote controls and improves user comfort in smart homes and work environments. BACKGROUND Modern environments are increasingly equipped with multiple electronic devices such as televisions, air conditioners, lighting systems, fans, and smart home devices. These devices are typically controlled via separate remote controls or interfaces, leading to operational complexity and inconvenience. Existing alternatives such as mobile applications and voice assistants are heavily dependent on connectivity, can cause latency, and often lack intuitive physical interaction. Wearable devices like smartwatches only offer partial solutions, are relatively bulky, and are not optimized for precise, energy-efficient, and direction-dependent control. Therefore, there is a need for a compact, ergonomic and efficient portable device that can seamlessly control multiple devices using intuitive gestures and voice commands, while ensuring secure communication and energy efficiency. SUMMARY OF THE INVENTION The present invention provides an IoT-enabled smart ring configured as a universal remote control. The smart ring integrates a multi-sensor system, an embedded processing unit, and a hybrid communication module to detect user movements, interpret commands, and transmit control signals to various electronic devices. The smart ring features an adjustable and lightweight design to ensure comfortable wear for different finger sizes. The system connects to a mobile application that allows for the assignment of device-specific frequencies, the encryption of control signals, and the customization of gesture and voice commands. In operation, the smart ring acts as an intermediary control interface. User input in the form of gestures or voice commands is recognized, interpreted, and then transmitted as corresponding control signals, either directly or via the mobile application. This eliminates the need for multiple remote controls and provides a unified control mechanism for various devices. DETAILED DESCRIPTION The IoT-enabled smart ring includes several key components: 1. Ring structure: • Made from lightweight materials such as polymer composites, metal alloys, or hybrid materials • Adjustable or expandable design to fit different finger sizes • Ergonomic design for comfortable and long-lasting wear 2. Multisensor system: • Motion, orientation, and acceleration sensors for gesture recognition • Proximity sensors for direction-dependent device selection • Optional touch-sensitive surfaces and flex sensors for finger movement detection • Optional environmental or biosignal sensors for context-aware functions 3. Processing unit: • Interpretation of gestures and conversion into control commands • Energy-efficient low-power architecture • Optional integration of machine learning functions for adaptive gesture recognition and personalization 4. Communication module: • Supports multiple transmission protocols, including infrared (IR) for older devices and wireless communication for IoT devices • Directional signal transmission via pointing function for precise control 5. Integration of a mobile application: • Assignment and storage of device-specific control frequencies • Encryption and secure coding of control signals • Adaptation of gesture and voice commands • Synchronization with multiple devices within a network 6. Voice command function: • Processing of voice input via a connected mobile device • Assignment of voice commands to predefined actions • Execution via the smart ring as a physical interface 7. Energy supply system: • Rechargeable battery and energy management module • Optimized for low energy consumption • Optional energy harvesting systems 8. Additional features: • Haptic feedback for confirming commands • Adaptive learning to improve gesture accuracy • Integration with augmented or mixed reality platforms via mobile interfaces OPERATIONAL PROCESS The user performs a predefined gesture or enters a voice command. The sensor system detects movement, orientation, or input. The processing unit interprets the input and generates a control command. The communication module transmits the signal to the target device. The mobile application enables mapping, encryption, and customization. The system provides feedback (e.g., haptic) to confirm execution.
